Def Tank Level Sensor

During operation exhaust gas after filtering through the particulate filter flows to the scr chamber where a dose of def is injected.

Def tank level sensor.

The following codes indicate that there is a defect in the level sensor inside the tank. The full tank assembly includes a header unit and sensors to measure urea levels temperature and quality. I find that my diesel exhaust fluid quality temperature says it is 32 degrees fahrenheit the quality percent is zero the tank level is 8 percent and i can see that in the tank it is full of def. They measure the change in capacitance between two plates produced by changes in level.

What has happened is cummins has put in a substituted value during this. In the event that you would need to replace the def tank level sensor see instructions below. The tank temperature says it s at 68 degrees fahrenheit. Relieve pressure from cooling system by removing pressure cap from surge tank.

Applications tank level monitoring in chemical food water treatment power and brewery industries. Park the bus on a level surface apply parking brake switch engine off remove ignition key and chock wheels. There are line options offered in nylon and ethylene propylene diene monomer epdm materials for both purging and non purging dosing systems. All in one solution for def tank.

A typical scr system includes a storage tank for diesel exhaust fluid def the scr chamber with catalyst an injector sensors nox analyzer wire connections and a control unit. Capacitance level sensors operate in the way that process fluids have dielectric constants significantly different to air. Urea level sensor length 300mm to 900mm urea temperature urea concentration detection of unauthorized fluids urea suction line with integrated filter urea return tank thawing using engine cooling system tank vent factory calibrated in compliance with din70070 iso 22241 standards. Negative cable first then positive 3.

Def tank level sensor replacement 1. 203c11 203d12 4bac 4d10 p203a p203d p209f code description. New for 2016 epa regulations def tank sensor assembly for level and temperature now fitted with quality sensor quality sensor must detect 32 5 concentration of def use def meeting iso22241 specifications for purity and composition store def in a cool dry well ventilated area out of direct sunlight.
